Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	Note 10: Income Taxes We file income tax returns in the U.S. federal jurisdiction and various state, local, and non-U.S. jurisdictions. We are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations in most major taxing jurisdictions for years before 2007. The U.S. examination of certain matters related to tax years 2008-2009 that were not settled as part of previous examinations remains in progress. Management believes it is reasonably possible the remaining 2008-2009 tax matters could be concluded within the next 12 months. However, resolution of these matters is still dependent upon a number of factors, including the potential for formal administrative and legal proceedings. As a result, it is not possible to estimate the range of the reasonably possible changes in unrecognized tax benefits that could occur within the next 12 months related to these years, nor is it possible to estimate reliably the total future cash flows related to these unrecognized tax benefits.

Note 10: Income Taxes

We file income tax returns in the U.S. federal jurisdiction and various state, local, and non-U.S. jurisdictions. We are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations in most major taxing jurisdictions for years before 2007.

The U.S. examination of certain matters related to tax years 2008-2009 that were not settled as part of previous examinations remains in progress. Management believes it is reasonably possible the remaining 2008-2009 tax matters could be concluded within the next 12 months. However, resolution of these matters is still dependent upon a number of factors, including the potential for formal administrative and legal proceedings. As a result, it is not possible to estimate the range of the reasonably possible changes in unrecognized tax benefits that could occur within the next 12 months related to these years, nor is it possible to estimate reliably the total future cash flows related to these unrecognized tax benefits.
